Hello,
I installed OpenVPN on a Ubuntu machine, and generated certificates to allow another Linux client to connect. Verified it's working, and the client is forced to use the VPN tunnel.
Now that it's working I'd like to generate certificates to allow me to add additional clients. I tried this by going to /etc/openvpn/easy-rsa and running 'build-key clientname'. I received a message about needing to source vars and .clean-all first. So I ran these commands (knowing that the certificates in the keys folder had already been moved out). Then I tried to generate the client certs again. This time I received a message about missing the CA certs and the private key. I then moved ca.* & dh1024.pem back over to the keys folder and tried again. Now I get a message 'Unable to load CA Private Key 140431349081752:error:0906D06C:PEM routines:PEM_read_bio:no start line:pem_lib.c:701:Expecting: ANY PRIVATE KEY
Keys are still generating, but I'm guessing they're not valid. In order to generate additional client keys, do I need to re-generate server cert, CAs, and DH Keys? Or am I missing something else?
Thank you!

OpenVPN to be run from a non-administrator account. OpenVPN to be started automatically on system startup. This is often preferred on the server machine, as well as any machines which will be constantly connected to the server. Run the Windows Service administrative tool: Press Windows Key + R Type 'services.msc'. Jun 30, 2016 This is a demo on how to generate server and client certificate for OpenVPN. This is a demo on how to generate server and client certificate for OpenVPN. OpenVPN Server in CentOS 7 Part 5.
In the example I followed, the server certs (including the DH pem file) were moved to /etc/openvpn. Client certs were moved elsewhere.Now that it's working I'd like to generate certificates to allow me to add additional clients.

Introduction
Static key configurations offer the simplest setup, and are ideal for point-to-point VPNs or proof-of-concept testing.
Static Key advantages
- Simple Setup
- No X509 PKI (Public Key Infrastructure) to maintain
Static Key disadvantages
- Limited scalability — one client, one server
- Lack of perfect forward secrecy — key compromise results in total disclosure of previous sessions
- Secret key must exist in plaintext form on each VPN peer
- Secret key must be exchanged using a pre-existing secure channel

Simple Example
This example demonstrates a bare-bones point-to-point OpenVPN configuration. A VPN tunnel will be created with a server endpoint of 10.8.0.1 and a client endpoint of 10.8.0.2. Encrypted communication between client and server will occur over UDP port 1194, the default OpenVPN port.

Generate a static key:
Copy the static key to both client and server, over a pre-existing secure channel.
Server configuration file
Client configuration file

Firewall configuration
Make sure that:
- UDP port 1194 is open on the server, and
- the virtual TUN interface used by OpenVPN is not blocked on either the client or server (on Linux, the TUN interface will probably be called tun0 while on Windows it will probably be called something like Local Area Connection n unless you rename it in the Network Connections control panel).
Bear in mind that 90% of all connection problems encountered by new OpenVPN users are firewall-related.
Testing the VPN
Run OpenVPN using the respective configuration files on both server and client, changing myremote.mydomain in the client configuration to the domain name or public IP address of the server.
To verify that the VPN is running, you should be able to ping 10.8.0.2 from the server and 10.8.0.1 from the client.
Expanding on the Simple Example
Use compression on the VPN link
Add the following line to both client and server configuration files:
Make the link more resistent to connection failures
Deal with:

- keeping a connection through a NAT router/firewall alive, and
- follow the DNS name of the server if it changes its IP address.
Add the following to both client and server configuration files:
Run OpenVPN as a daemon (Linux/BSD/Solaris/MacOSX only)
Run OpenVPN as a daemon and drop privileges to user/group nobody.
Add to configuration file (client and/or server):
Allow client to reach entire server subnet
Suppose the OpenVPN server is on a subnet 192.168.4.0/24. Add the following to client configuration:
Then on the server side, add a route to the server’s LAN gateway that routes 10.8.0.2 to the OpenVPN server machine (only necessary if the OpenVPN server machine is not also the gateway for the server-side LAN). Also, don’t forget to enable IP Forwarding on the OpenVPN server machine.
